VAR-201404-0040

Vulnerability from variot - Updated: 2025-04-12 23:29

Cisco IOS before 15.3(2)S allows remote attackers to bypass interface ACL restrictions in opportunistic circumstances by sending IPv6 packets in an unspecified scenario in which expected packet drops do not occur for "a small percentage" of the packets, aka Bug ID CSCty73682. Cisco IOS Has an interface ACL A vulnerability exists that circumvents the restriction. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. This issue allows remote attackers to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is tracked by Cisco Bug ID CSCty73682
